GoDAO in Uruguay

My name is Daiana and I am from Uruguay. I started treatment with Adriana last year, and began taking GoDAO shortly afterward. It has helped me a lot — both in feeling better and in being able to manage daily life, in addition to following a diet, which is essential, and especially in handling situations where there aren’t many choices available.

Even though I am on the other side of the world, I would like to thank and highlight the constant support I have received with orders, timely deliveries, and all the necessary arrangements, so that the product can reach the person who then brings it to my country.
Thank you very much for everything.

GoDAO works and is effective. Great service

02/09/2025 - I switched to GoDAO following the suggestion of the DAO Deficiency Institute team, and it turned out to be a great decision. GoDAO is effective, it really works, and it has helped me be able to eat foods without experiencing histamine-related symptoms afterwards. The service was very attentive and the order arrived within 24 hours by courier. The box contains tablets for one month; they are small and easy to carry. In addition, you receive a reminder when it is time to renew your order, so you don’t have to worry about keeping track of it. GoDAO has greatly improved my life.

With Go Dao I really don't have to worry about social meals

01/09/2025 - With Go Dao I really don't have to worry about social meals or birthday's parties because it just helps me with all the severe symptons I have had. So grateful to have come across the only doctor in Portugal that has the studies of hystamine intolerance, because for sure it helped me improve the quality of my life.
